Tag

A collection of key:value pairs associated with an AWS resource. The key:value pair
can be anything you define. Typically, the tag key represents a category (such as
"environment") and the tag value represents a specific value within that category
(such as "test," "development," or "production"). You can add up to 50 tags to each
AWS resource.
